The title complex, [Nd(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, contains two Nd atoms, six 4-hy-droxy-phenyl-acetate (hpaa) anions, two 4,4'-bipyridine mol-ecules (bipy) and two water mol-ecules; an additional water mol-ecule of solvation is also present in the crystal structure. Each of the Nd(III) ions is nine-coordinated by seven O atoms from four hpaa ligands, an N atom from a bipy ligand and an O atom from a water mol-ecule in a distorted tricapped trigonal-prismatic geometry. The hpaa ligands are coordinated to the Nd(III) ions in the bridging and bridging tridentate modes. Extensive O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonding stabilizes the crystal structure.
